The GZ34 isn’t a very talked about tube, but it is one of the most common rectifier tubes found in audio, especially in guitar amps. Rectifier tubes were some of. Page 1. Page 2. Page 3. Page 4.

The story is different with a two-phase rectifier see later. Collection of Marco Lagendijk NL.
Collection of Philip Coller F. Required Diode Ratings The diodes in a two-phase rectifier need to have an average forward current rating that comfortably exceeds the maximum DC load current in your circuit. Valve rectifiers can’t handle the high current levels that silicon diodes can. The peak AC voltage is equal to 1. The diodes must also have a Reverse Repetative Maximum Vrrm rating that exceeds the peak-to-peak AC voltage measured from one end to the cente taptwice the value needed for a bridge rectifier.
Bridge Rectifier A bridge rectifier is used to rectify AC from a transformer with a single winding i. The Valve Wizard How to design valve guitar amplifiers! The DC voltage will therefore fall to: Vaccum rectifiers must not be ‘hot switched’, i.

Valve rectifiers sometimes also need current-limiting resistance to protect them see shortly from excessive ripple and surge currents. Collection of Wolfgang Bauer A. Beginners sometimes call the two-phase rectifier datasyeet ‘full-wave rectifier’. This can be done by adding a 10nF to nF capacitor in parallel with each diode. Collection of Georges Werts B.
In the hybrid bridge hybridge? Under light loading the DC output voltage will again be equal to: Datashedt forget about adding fuses! Collection of Georges Werts B. Antique radios, Old Time Radios.
TDSL Tube data [GZ34]
In addition to the maximum AC voltage and DC current ratings, valve rectifiers have two other ratings that must be observed: At any time, one diode is on and the other is off. Valve Rectifiers Ordinary valve rectifiers contain two diodes which share the same cathode and heaterin one bottle.
Again, you don’t have to worry about peak and surge current ratings, provided the average current rating is adequate for the job. Two full-wave rectifiers orientated in opposte directions creates a bipolar supply positive and negative DC.
You will find thousands of tubes or valves with interesting links. For example, the GZ34 is rated for only mA average.
As a rough approximation, at full load the DC output voltage will normally be between 1 and 1. Collection of Karlheinz Fischer D.
However, we must ensure that the voltage is shared at least roughly equally. The data sheet will present table or graphs showing the minimum limiting resistance needed for a given application. Collection of Tomasz Szczesniak PL. As a rough rule datzsheet thumb, at full load a valve rectifier will produce a DC xatasheet that is between 1 and 1. Therefore, we can’t use the 1N if the advertised transformer voltage is greater than Vrms.

Collection of Alberto Ammendola I. Sovtek; Saratov National Electronics, Inc. The attached pdf gives a brief overview, but other factors such as series resistance and capacitor loading must also be considered.
You even can look up radio models with a certain tube line up. Telefunken Werkstattbuch Wolfgang Bauer.
